Hi guys.
I know this subject must have been discussed before, I do not mind if you point me out to the right direction.
Anyway, I am seriously thinking solar panels for my Super Maramu.
The goal is to be able to at least run the fridges and sails and to minimize the use of the generator but I do not want to have an arch and do not one have Wanderer looking like a Xmas tree. I guess a little guidance to a minimum of power I should consider would be great
I really love the shape of my boat and the uncluttered and uncrowded lines.
My ideal of solar panels location would be on top of dog house or/and on the deck just in front of the windscreen. 
The question is, how much watts can I fit onto that area and how bad would be the shading from the boom. If someone has the time to send me some pictures of their setup, I would be most grateful.
Thank you.

Before leaving the boat for an extended period of time I have always used 30ml Sodium Metabisulphite in 7.2l water (approx. 1 bucket), circulated through for half an hour, then allowing the bucket to drain, leaving the membranes flooded with the solution.

Subject: Re: [AmelYachtOwners] Membrane Tube end caps

 

One of the things that have not been mentioned in this Topic is the possible causes of the deterioration of some materials used for endcaps.

 

There is anecdotal evidence that points to Sodium Metabisulfite, the pickling chemical as being a cause, especially when it is mixed in a solution greater than recommended by Dessalator. IMPORTANTLY, the smaller watermakers (50-60 liter) have less than 1/3rd the internal volume that the larger watermakers (150-250), yet the recommended dosage is the same! This makes no sense to me. Additionally, there are some who believe if a small amount of pickling agent is good, more is better. BeBe (SM 387), with a D160 watermaker, had this "more is better" problem for the first 1.5 years of her life. She was cared for by an "experienced" guy in Tortola. He was one of those who believed, more is better. During his this time,  BeBe's owner only used BeBe 3 or 4 times for 2 weeks or less.  After each use, he had the caretaker pickle the watermaker. Within a few months of our ownership, the membranes needed replacing, and the white endcaps were deteriorated around the interconnect bobbin. When we bought BeBe, the watermaker had 34 hours on the meter, but the endcaps and the membranes needed replacing. I estimate that, except for a few weeks, the system was filled with a very high solution of Sodium Metabisulfite.

 

I replaced the white end caps with the "new" black end caps and had no issues for almost 11 years of ownership. During that ownership, I never used Sodium Metabisulfite. I replaced the membranes about every 3 years. I replaced them when the TDS neared 300ppm. This was my preference. Interestingly some Spectra watermakers have an auto-rejection system that rejects product water at 750ppm (default). Some watermaker manufacturers have said that any ppm that is under 1000ppm is safe. WHO states that 750ppm is safe, but recommends a daily intake limit at 500ppm. The efficiency of membranes, in terms of ppm changes with age. The slow creep of ppm will not be noticed. You should check ppm continuously.

 

Lastly, I have found Dessalaltor to be responsive to our needs. And, please remember this: "We encourage postings which will genuinely help Amel owners source needed parts and services. We encourage you to support the Amel brand and be respectful to the brand in your postings. Care should be taken to not post anything that could be considered offensive or derogatory regarding Amel, any Member, or Sponsor. Please refrain from political issues, rude, or inappropriate language. Please refrain from criticism of persons or businesses in which you may have experienced unsatisfactory results, because it would be one-sided, without the ability of the other side to respond."

 

BTW, Dessalator is the supplier of choice of many Super Yachts.

Until now I did not find a cruiser perfectly happy with his or hers watermaker. These things are extremely sensitive to bad treatment and treating them well can be a drag after so much time.
From my point of view there are a few things Desalator could improve with very little cost. I appreciate they don't change the product every two years and forget about spareparts for the installed base, like many companies do, but there are some obvious thing they could improve like many Amel owners already did themselves.

Thanks to you Ian.
I am planning to cross the Atlantic in december and to go to Florida. 
I see that you are in Fort Lauderdale, so we will be able to meet each other in the real world :-) 
All the best,

I think it‘s unfair to broadcast such negative things about Desal, . Amel is still installing Desal Watermakers and I had very good experiances with SAV Dessalator. Mr Wagner jun. and his team is helpful and have a amazing knowledge about H2O makers.
So pls. we know us , be specific what was your problem with SAV. Maybe I can help you, cause I have a very good contact with Wagner

Hi Bill,

 

Thanks.  I also took the entire holder to the shop… to verify the interior measurements.  I suspect the new ones will be made to a closer tolerance.

 

Dessalator after sales service has been non existent.

FYI, Dessalator originally made the membrane tube end caps out of white nylon. Emek copied Dessalator. Dessalator's choice of Nylon proved to be the wrong choice. Dessalator later made end caps from a harder material which was black. I am not sure of what the black material is, but, in my experience is that there have been very few issues with the Dessalator black end caps.

Hi Danny,

I made a change to the endcaps to solve this problem once and for all. I drilled 3 holes in the side of the cap, making sure not to drill too deep and ending up in the inner cavity. Then I cut some thread in the hole (M6) and put a very short bolt with a hex head in the hole using 3M 5200.
Now I have three points on the cap I put the blade of a screwdriver to and gently tap the cap from the tube.
What Desalator should have done is make the cap diameter lager then the tube diameter so you can develop some grip on the cap. Also the price is insane.
I'm a bit underwhelmed with the way this watermaker is designed, although the dual voltage thing is very clever. The control logic is well below par for the price I would say.

Matt,

1. We were never in cold climates
2. We were on the boat continuously with very few exceptions
3. I installed a 24-volt timer and solenoid valve to flush 2x weekly when we were off the boat for a month

Hi Arnold;

 

I had placed an order for about 10 packs a few years ago. At the time they were 5 Euros per pack. I do see now that they have increased their price to 27.53 Euros on their website. That is an unexpected increase.

 

Happy Sailing;

Paul,

 

I was referring to the fact that Dessalator recommends using the ST2 sterilizing cartridge and 1 packet of their "sterilizing" powder." This is regardless of the size.
